I too am a straight-through user. However, when I got my first 'big' apeture finder (40mm & over), the higher number of visible stars prooved overwhelming. Made my own erect image straight through out of a chopped pair of 7X50 binos, including adding the crosshairs to it. Did it after finding out the price of the off the shelf unit. This unit ended being cheaper than an inverted image of 50mm.
I also use an RDF mounted to a 76mm reflector finder in turn mounted to the back-end of my big dob. Very quick, for me anyway.
Both of these set-ups are on my dob.
